Balancer throws "Not a host:port pair" unless port is specified in
fs.default.name
----------------------------------------------------------------------------------
Key: HADOOP-5463
URL: https://issues.apache.org/jira/browse/HADOOP-5463
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.19.1
Reporter: Stuart White
Priority: Minor
If fs.default.name is specified as only a hostname (with no port), balancer
throws "Not a host:port pair" and will not run.
Workaround is to add default port 8020 to fs.default.name.
According to Doug: "That's the work-around, but it's a bug. One should not
need to specify the default port number (8020)."
According to Raghu Angadi: "Balancer should use NameNode.getAddress(conf) to
get NameNode address."
